The range should be 0-10 ppm, or 25-1000ppm.

Jackson Turbidimeter measures turbidity 25-1000 ppm.
Hellige Turbidimeter measures turbidity 0-50 ppm.
Baylis Turbidimeter measures turbidity 0-2 ppm.

As per my knowledge, Baylis turbidimeter cannot measure turbidity more than 2ppm and Hellige turbidimeter cannot measure turbidity more than 50ppm. And the question asked is upto 1000ppm.

Jackson's Turbidimeter:

It is used to measure high turbidity, i.e. 25 " 1000 mg/l.
It cannot measure turbidity less than 25 mg/l.

Bayli's meter:

It is used to measure low turbidity, I. E less than 10 mg/l.

Ratio Turbidimeter:

When a turbidity meter is measuring with "ratio on' it will use data from several detectors and take an average, in order to correct for changes caused by this particle size difference.

Nephelometer.

This works on the principle of light scattering. It is a digital electronic device that measures low turbidity in water with very high precision in no time.

It measures turbidity in terms of NTU (Nephelometric Turbidity Unit).

Jackson turbidimeter is the right answer.

It is requested to the admin, if you upload any question then an explanation regarding that particular question should also be uploaded along with the question so that such confusion among the aspirants couldn't be developed.

Jackson turbidimeter will be the answer.

Thanks @Arun.

Jackson turbidimeter will be the answer.

Because Jackson can't measure turbidity below 25 units, so the answer is Baylis.

Option B is correct.
